 note = {This paper proposes antenna arrangements which realize a unitary matrix for 4×4 multiple-input multiple-output (MIMO) system in line-of-sight (LOS) environment. It is shown that the channel matrix is unitary matrix by properly adjusting the element spacing and the high channel capacity is obtained by the proposed antenna arrangements with directional antennas even if the multipath signals in indoor scenario are considered.},
